<p>An output circuit comprises a transfer gate (6) connected between an input terminal of the output circuit and an input of an output buffer circuit, a protection circuit (7) adapted to be actuated to turn off a transistor (P1) constituting the output buffer when a potential higher than an operating source voltage of the output buffer circuit is applied to an output of the output buffer circuit and a control circuit (5) adapted to turn on the transfer gate (6) in response to a signal input to the input terminal and off the transfer gate (6) when the protection circuit (5) is actuated. <IMAGE></p> |
